哥斯达黎加采购需求：铜版纸、无碳纸、彩印纸、复印纸、口杯纸、白板纸

I am looking to source a quantity of white paper with a weight of either 56 or 58 grams for use in manufacturing waiting notebooks. It's important that the paper quality meets industry standards to ensure durability and a good writing experience for the end users. The specifications are crucial, so I'm interested in understanding the types of paper you have available, including any relevant details about texture, brightness, and any special properties it may possess. Additionally, I'd appreciate information on your pricing structure for bulk orders, lead times for delivery, and any minimum order quantities that may apply. If you offer samples, that would be helpful for evaluation. Please also inform me about your payment terms and any other details that might facilitate a smooth procurement process. Looking forward to your prompt response.
